1,4-Dichlorobenzene (p-Dichlorobenzene) is an organic compound with the chemical formula C6H4Cl2. It is a white crystalline solid with a strong, characteristic odor. This compound is widely used as a disinfectant, deodorant, and pesticide, particularly in mothballs and air fresheners. It is also an important intermediate in the production of other chemicals, including polymers and agrochemicals.
